Abstract
In OFDM transmission, performance is degraded by the existence of time domain impulse noise because its influence spreads over the whole carriers by the DFT operation in the receiver. Especially influence of the impulse noise whose amplitude is large. In this paper, the scheme of improving influence of impulse noise is proposed. In the proposed scheme, the symbols after decision are re-modulated to generate a time domain signal to replace the samples that are degraded by the impulse noise in the time domain. The time domain signal where the influence of the impulse noise is reduced is demodulated again.
